... and the only reason for it to be four columns is that you personally find it hard to read, or do you have another, more compelling argument against using 8 column tabs?

Personally, I find 8 columns to be an incredible waste of horizontal space. I frequently place editor windows/panes side by side, and using 8 columns or spaces wastes valuable screen real estate.

But this isn't just a reaction rooted in practicality. To me, this looks and feels absurd. It kind of hurts to read. Again, this is just my personal take.

I prefer scope indentation of any kind to render as 4 spaces, but I'm okay with 2 as well.

I agree. For me, I want enough indentation to make the structure obvious. 8 columns is way overkill in that regard.

I'm kind of surprised that 8 column tabs is even being discussed, I thought 2 or 4 were the normal values?

Yes, it was just a personal opinion.

But not personal enough not to be the basis for an argument about what github should do to display Go code.

What are you arguing about exactly? Am I not allowed to think Github should display them as 4 columns?
